+ * xcompmgr.c: (make_gaussian_map), (make_shadow), (shadow_picture),
+ (solid_picture), (discard_ignore), (set_ignore), (should_ignore),
+ (win_extents), (border_size), (paint_all), (repair_win), (map_win),
+ (unmap_win), (get_opacity_prop), (determine_mode), (add_win),
+ (destroy_win), (error), (main):
+ Ok, this synchronizes all of my changes for the last many months.
+ Has code to do server-based shadows (SHARP_SHADOW).
+ Has code to try and ignore appropriate errors (helps somewhat).
+ Has code to handle global window translucency.
+ Lots of other minor changes.
